how air conditioning transformed the u.s. economy
Heat waves can prove that there is no fun in the heat.
People become dull and irritable.
Work hard, concentrate hard, and it becomes difficult to do anything.
The risk of high temperature when the temperature exceeds 100 degrees
The number of related deaths has increased sharply.
In fact, even studies have shown that extreme heat kills a country\'s livelihood.
A 2008 study by three economists led by Benjamin Jones of Northwestern University found that in hot weather, economic output in poor countries would fallthan-average years.
Not only did drought kill crops.
The decline in industrial output has increased the likelihood of political unrest.
It is strange, however, that this happens mainly in poor countries --
Rich countries are much more immune to high-temperature penalties.
Of course, an explanation for this difference is air conditioning.
Today, most Americans can minimize exposure to sultry weather.
We can wake up in the thermostat.
Tune the family and hop on our air conditioner
Drive to our cool office.
Of course not everyone is so lucky.
Many people do not have office work and thousands of people in Washington are out of work due to power outages. C. without power—
But indoor climate control is a feature of Western industrialized countries.
The economic benefits seem to be great.
Stan Cox lists in his fascinating book, lost our cool, a series of ways air conditioning changes AmericaS. economy.
The following is a description of the National Museum of Architecture before the invention of AC in the 1920 s: After the discovery of fluorine chloride in 1928, everything changed (CFCs)
Used as a coolant in the air. conditioning (
We learned later that we had a hole in the ozone layer).
Retail stores can now operate for one yearround.
Americans may flock to areas south and south west that are not friendly.
Cox even thinks air conditioning is a major factor in the revival of the sun.
But there\'s another side.
All this will prove unsustainable.
The amount of energy consumed in the United States. S.
According to Cox, the number of air-conditioned households has doubled over the past 12 years and now accounts for nearly 20% of our electricity consumption.
More importantly, developing countries like China and India want something that is considered absolutely necessary.
According to a recent report by the New York Times, air-conditioning sales in the two countries increased by 20% per year.
If all these countries continue to burn coal to meet the demand for indoor cooling, there will be more carbon dioxide in the air. (
The friendly HFCs used in these devices are also very effective greenhouse gases. )
This means that a hotter planet will need more air conditioning to survive.
Remind me how often the days of 100 degrees Fahrenheit in the United States will become if carbon emissions continue to grow at their current rate: the current \"abnormal heat wave\" will become a normal state
Sixth in D. C. (
Except for all other climate consequences --sea-
Rising, drought, agricultural disruption
This may prove more difficult to adapt. )
In our endless pursuit of cooling ourselves down, we have succeeded in heating up the world.
So is there a way to break this cycle? One oft-
The option discussed is to make the air conditioner more energy efficientefficient.
This may mean more than just patching of existing devices.
In countries like Japan and South Korea, many homeowners find it a waste of time to cool the entire vacant house at a time, and they prefer to focus on individual rooms where people actually sit.
Like the factory, better insulation and ventilation can reduce the demand for communication
\"Green Roof\" covered by naturally cool buildings \".
There are also good alternatives to conventional air conditioning, including ground air conditioning
Source heat pump to transport hot air from the house to the ground in summer.
In his book, Cox suggests going further: he believes that it may be better in some ways if people learn to reduce their dependence on manual temperature control.
There is little evidence that keeping office temperatures at cold levels can improve productivity.
In fact, when the human body is not covered with air conditioning all the time, it may actually be healthier.
For example, some researchers even believe that our dependence on indoor cooling can help trigger a obesity epidemic.
Some parts of developed countries are slowly working to ease their reliance on air conditioning.
In Japan, the government has put pressure on businesses to keep their thermostats at a mild 81 degrees Fahrenheit in the summer, Cox noted.
After the initial resistance, the merchant took off his suit coat and adjusted it.
Similarly, shopping malls in Hong Kong now promise to lower air conditioning to save energy.
Nevertheless, the temperature in many parts of the United States reaches a dangerous high level of the day (
The height is close to 5 fin D. C. )
Calling for protection is a tough sale.
The main thing to note is how different Today\'s heat wave is from 1920
Because we have adapted a lot.
